The Hobbywing 30402651 JEZRUN-3660SL-4000KV-G2 delivers crisp top-end speed for serious RC drivers who want dependable sensorless performance. Its 4000KV rating and 4-pole design combine to give quick throttle response and solid acceleration in a 1/10 package.

Built for Torque and Responsiveness

Engineered with a 36mm outer diameter and 60mm length, this motor strikes a practical balance between torque and rpm. The 5mm shaft allows easy fitting of common pinion gears for a variety of drivetrain setups.

Most 1/10 electric touring cars accept this motor thanks to its standard 36 x 60mm casing and 5mm shaft, but check your mount spacing and pinion clearance before fitting.
Use a brushless ESC rated for 2-3S LiPo with suitable current capacity; set motor timing low to medium to keep heat manageable while retaining crisp throttle feel.
Ensure good airflow through your chassis, avoid overly aggressive gearing, and consider short cooling breaks between runs to reduce temperature buildup.
